Response of Indian mustard cultivar RH 749 to different fertility levels under tarai conditions of Uttarakhand

Abstract

A field experiment entitled “Response of Indian mustard cultivar RH 749 to different fertlility levels under tarai condtions of Uttarkhand” was conducted at N. E. Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during rabi season of 2016-17. The experiment was laid out in factorial randomized block design comprising twelve treatments with three replications. The nitrogen, phosphorous and potassium were applied through urea, SSP and MOP, respectively. The results revealed that significantly higher seed yield (2135 kg ha-1) was obtained with the application of 120 kg nitrogen per hectare which was 17.5% and 29.2% higher over application of 100 kg and 80 kg nitrogen per hectare. This increase is due to higher values of yield attributing characters viz. number of siliquae per plant (326.7), number of seeds per siliquae (15.4), length of siliqua (4.3 cm), 1000-seed weight (4.3 g). Significantly higher oil yield (793.2 kg ha-1) was also recorded with the application of 120 kg nitrogen per hectare. Therefore, it can be concluded that Indian mustard RH 749 performed well with the application of 120 kg nitrogen along with 40 kg phosphorous under tarai conditions of Uttarakhand.
